Borel-Écalle Resummation of a Two-Point Function

We provide an overview of the tools and techniques resurgence theory used in Borel-Ecalle resummation method, which we then apply to massless Wess–Zumino model. Starting from already known results on anomalous dimension model, solve its renormalisation group equation for two-point function a space formal series. show that this solution is 1-Gevrey Borel transform resurgent. The Schwinger–Dyson model prove asymptotic exponential bound transformed star-shaped domain suitable ramified complex plane. This proves summable.
